The Fundamentals of Camera Movement

Video camera movement is used for many purposes. It may be used to make an object appear to be bigger or smaller. 

It may be used to make things blurred, scary, or just different. Camera movement techniques are often used, however, to tell a story.
Learning camera movement fundamentals isn't hard. The various camera movement techniques are done either with a mounted camera, a moving camera - where the camera and the photographer move together, or movement of just the camera lens.


Practicing the various camera movement fundamentals will help you learn which camera movement techniques work best for you.
 



 
Technique 1: Mounted Camera Pan
Mounting the camera on a tripod, simply move the camera horizontally from left to right. Pan shots are used to show the viewer more of the scenery. This technique is also often used to show views from high places, such as overlooks. Pan shots should begin with a still shot, then pan, then finish with a still shot. You should practice panning at various speeds until you find the speed that works best for you.
 

Technique 2: Mounted Camera Tilt
A tilt done with a mounted camera is quite simple. You just move the camera up or down, without lowering or raising the position of the camera. This is must like panning, only it is done vertically. This video camera technique is used to follow the subject that you are photographing, or to show the viewer a large object from top of bottom - or from bottom to top.
You should note that when you tilt from bottom to top, the object looks larger or thicker. When you tilt from top to bottom, the object looks smaller or thinner. As with panning, you should begin with a still shot, tilt, then stop on a still shot. Again, practice this technique at various speeds until you find what works for you.
 

Technique 3: Mounted Camera Pedestal
This video camera technique is pretty much the opposite of the tilt technique. You do not tilt the camera, but you either raise or lower the position of the camera. This technique is simply used to get the proper view that you are looking for.
If you wanted to shot pictures of a baby, you would want to lower the camera. If you wanted to shot a tall person, you would raise the height of the camera. The purpose would be to make it appear that the subject is 'eye to eye' with the viewer.
 

Technique 4: Moving Camera Dolly
This video camera movement technique involves the use of a camera dolly, like the camera dolly's you might see on a movie set. You can make your own dolly with a wheelchair, a scooter, a skateboard, a rolling cart, or many other devices that have wheels.
This video camera movement technique is used to follow your subject. The use of a dolly opens up many possibilities, especially when used in conjunction with other techniques. Remember that you will want to be able to roll backwards as well as forward. Practice using this technique, and once you have it down, try mixing it with other techniques.
 

Technique 5: Moving Camera Floating Stabilizer
Floating stabilizer devices are used to follow a subject around twists and turns. The stabilizer is strapped to the photographer, and the camera is mounted to the stabilizer with metal jointed which are controlled by gyroscopes.
This video camera movement technique is a step up from the dolly technique. The movement of a dolly is limited, floating stabilizer devices remove those limitations. As with the dolly technique, you should learn the video camera movement fundamentals of this technique, then try mixing it with other techniques to get different effects.
 

Technique 6: Moving Camera Boom
A camera boom is a smaller version of the cranes that are used for construction. A camera boom is used to get a view of subjects or scenes from above. These are commonly used in filming movies, and the boom moves up, down, and around.
 

Technique 7: Moving Camera Handheld
Using this technique, the photographer simply holds the video camera, and moves wherever, and however, he needs to move to get the shot that he wants. When using this technique, you should avoid using the zoom feature on your camera. Zooming while using the handheld technique will make your shot appear to be shaky. Instead of zooming, move closer to the object you are shooting.
 

Technique 8: Camera Lens Zoom
You can get many different effects when using the zoom feature on your camera. This works well when combined with other video camera movement techniques. You should practice zooming at different speeds, as different situations will call for different speeds of zooming.
Zooming can create many different illusions, which can effect the viewers perception of size and distance. Alternately, zooming can be used to more adequately portray the size or distance to a viewer. It is recommended that you use a tripod when using the zoom technique.
 

Technique 9: Camera Lens Rack Focus
This is an interesting video camera movement technique, which can give your shots more impact. This technique calls for focusing the camera on one object in a close up shot, causing everything in the background to be out of focus, then causing the object itself to become out of focus while the background becomes in focus.
This is done by changing the focal length so that one object will go out of focus while another comes into focus. The two objects must be at a correct distance away from each other for this technique to work, and you will want to use a tripod for this type of shot.
 

Conclusion
Learn how to use all of the features on your camera, then combine the use of those features with different movements to get the most out of your shots. Video camera movement techniques can really spice up your home movies, and give them the style and flair that you see in Hollywood movies!

Corel VideoStudio Pro X4 Review

"How can I easily get the video off my camcorder, into the computer and produce a professional looking DVD? It’s so hard!"


Are you getting started with digital video and asking the exact same question?

You’ve seen how others create beautiful home videos all stored on gorgeous DVDs (with fancy DVD menus and all that) – so it can’t be that difficult can it?

4. Professional-looking Results
With professionally-designed theme templates and DVD menus in VideoStudio Pro, you’re not going to come up with boring, plain old DVDs. You get professional level stuff.
And if you don’t like the in-built effects, feel free to personalize your projects with easy-to-use creative options, adding titles, transitions and music tracks. You’ll not run of ideas because there are literally 100's of effects filters and content like overlay frames, objects and Flash animations to play around with.
Frankly, I sat there and played with my version of VideoStudio Pro for HOURS, just tinkering with the special effects – it’s that good.


Oh, I really need to tell you about this one. You know those vacation routes you see in videos which get traced on a map? Now you can do that, to show that you went from, say, San Francisco to Hawaii.
You can do this because VideoStudio Pro allows you to do paint, draw, or even write freehand on your digital video!




5. Share Your Video On YouTube Or DVD
And if you want in on the ‘web video’ revolution, VideoStudio ensures you’re no left out. In VideoStudio Pro, you can cut your movie and upload directly it to YouTube. Cool stuff and a great way to share your videos with others..
 
Sharing on YouTube or burning a traditional DVD - you decide.

If you prefer the traditional DVD format, you can simply choose to create stunning animated Hollywood-style menus. They are all in-built and for you to point and click. If you prefer, you can even send movies by email or share them on mobile devices.


6. Works With Cameras, Camcorders And Cell Phones
Some video editing packages don’t work with certain video sources. For example, I know of packages which don’t work with cell phones or digital cameras. VideoStudio Pro works with the whole gamut of devices out there. We’re talking about the ability to import photos and video from digital camcorders, the internet, TV, digital cameras and cell phones. Everything.


7. Really Easy To Use
You know, some folks I know get scared off by the ‘complexity’ of video editing packages. Some fear the video editing process so much that they ‘leave out’ video editing and keep the videos (unedited) in their camcorder! Or others ‘outsource’ the video editing to third parties.
 

The flexible user interface allows you to start editing in a matter of minutes

Let me tell you, don’t be afraid to use the video editing package. It’s loads of fun! VideoStudio Pro has a flexible user interface, clearly defined icons and guided workflows. Produce professional-looking movies or photo slide shows with the Movie Wizard. Burn video straight to disc with the DV-to-DVD Wizard - hook up your camcorder and in two steps you have a finished DVD. Two steps! Nothing could be simpler to use.


8. Powerful Creative Tools - If You Want To Experiment
If you’re a bit more in-depth in your knowledge of video editing, don’t think that VideoStudio Pro doesn’t allow you to ‘grow’ and experiment with advanced features.
There are powerful tools like sophisticated picture-in-picture and montage effects with transitions on overlay tracks, and audio/video cross-fades. You can also create animated titles and add color backgrounds. Plus there’s solid support for Dolby Digital® 5.1 Surround Sound audio.

And what about creative tools? Lots of them! You can paint, draw, or write freehand on video with the new Painting Creator. Make photo slide shows come to life with Auto Pan & Zoom. You know those ‘blue screen’ backgrounds you use in your video to overlay a background? Use the Chroma Key tools to replace those backgrounds.
Gosh, I could just go on and on about all the neat stuff in there. Sophisticated DVD menus with unique disc menu transitions, 100s of effects filters, and the ability to make your video look like old film with NewBlue® Film Effects filters (in the Pro X4 edition). See the old film effect on the right? That's what we're talking about!



9. End-to-end HD Support
There’s one more thing to say – and that’s concerning High Definition (HD). As you might know, HD video is now all the rage. Want to watch your home movie on a large flat panel TV? You’d better film it in HD to avoid a ‘poor quality’ look.

The good thing about VideoStudio Pro is that you can import video in leading HD formats, including HDV™, AVCHD and Blu-ray Disc®.
 
Editing HD video takes up TONS of computing power. And I mean TONS. If you have a powerful new PC, you’ll want to make full use of it by utilizing the dual-core and quad-core CPU capabilities in your machine. VideoStudio Pro provides native support for these CPUs so that editing HD content is fast and not agonizingly slow.
 
And if you want to produce a shining new Blu-ray disc instead of a DVD, VideoStudio Pro can do that too! I really find it amazing how Corel can roll out Blu-ray support so quickly – it just shows the amount of research that these companies pump into their products.
 

10. The Shortcomings?
Well, there aren’t much that I can think of. VideoStudio Pro is an excellent video editing package – perhaps the only shortcoming is the fact that it lacks the overall video editing power that a competitor package like Adobe Premiere Elements has.
However, you should remember that Adobe Premiere Elements is a touch more complicated for new users to get to grips with. What VideoStudio Pro lacks in in-depth video editing power, it makes up for in its supreme ease-of-use.

11. It's An Award Winner!
Ok, I know I’ve been ranting and raving about Corel VideoStudio Pro for quite a bit. And saying how good it is and all that.

But you know what? The truth is, the product is really very good. Corel took over this company called Ulead (which I’ve been an ardent fan of), took one of its flagship products (Ulead VideoStudio 11) and improved it to become Corel VideoStudio Pro X4.

They obviously have done something right, because Corel VideoStudio Pro X4 has garnered awards from CNET Download.com and PC Magazine.


Here’s what CNET (5 out of 5 rating) says:

"We like the new paint feature which lets you draw or write freehand on your videos making it easy to add thought balloons or draw your travel route on a map..."


And here’s what PC Magazine (4 out of 5 rating) says:
"This is a very good consumer-level video editor, and it's an especially fine choice for users with less-powerful PCs who want to edit HD video."




 
Conclusion
I think Corel VideoStudio Pro X4 is really a very good choice for beginner digital video enthusiasts who want simple-to-use features in their software but yet want the option to ‘grow’ into the product and try out advanced level stuff.

Some video editing software packages are too simple and don’t offer any creativity tools. Others are insanely complex and hard to learn. I think Corel VideoStudio Pro X4 has hit just the right balance between ease-of-use and complexity of its functions.
If you’ve just started out in digital video or are an intermediate level user, Corel VideoStudio Pro is hard to beat as a all round video editing tool.

Which Is The Best Video Editing Program?

Video editing programs are software which can be installed on computers to retouch the videos that have been recorded to make them polished and appealing for your viewers.
These programs are capable of editing video clips or full length videos from camcorders, digital cameras and even mobile phones, which are capable of recording video.
So which is the best video editing program? In my experience, a good video editing program should give a very intuitive and elegant user interface and allow you to accomplish editing tasks very quickly. However, they are also complex enough to let you experiment with advanced video effects if you so choose.
Let's take a more in-depth look at a list of 10 contenders for best video editing program. These are the tools I keep turning to as part of my video editing hobby.

1. Corel Video Studio Pro

One of my perennial favorites, Corel Video Studio Pro is one of the best among all the available video editing programs. With a very simple user interface, the software is capable of completing some complex video editing tasks with ease.
There are also a number of editing tools which are built-in and accessible via a feature called the "Movie Wizard". This wizard allows the users to very quickly put together a video which can be as long as full length movies.

The best part of the Corel VideoStudio is that the output can be saved in a number of formats which allows the viewers to watch the video on computers, TV or even video players for mobiles.
In addition, there are some other additional options like adding movie titles, seamless integration of music as well as creation of simple slide shows.
A great package that can be used by both novice and professional editors with ease. Check out my Corel VideoStudio review here.

2. Movavi I recently came across Movavi, an amazing piece of software. This is an all-in-one package of powerful yet easy-to-use tools for any video processing needs: edit, enhance, convert, burn Blu-ray Disc & DVD.

For starters, you can transfer video and audio between more than 170 media formats, including DVD and HD. You can also save video to than 180 portable devices, including the Apple iPod, iPad, iPhone, Sony PSP™, Zune, BlackBerry, etc.
You can easily create your video masterpiece using a customizable timeline and powerful collection of video editing tools: split, crop, join, rotate, and more. You can also enhance the video with built-in special effects.

Capture video into your PC? No problem. Movavi allows you to capture video straight from DV cameras and or TV-tuners. Save MPEG-2 TS and AVCHD video from camcorders to PC. Now you have a way to revive your old movie collection and family videos stored on VHS cassettes.
As for sharing that video of yours, Movavi allows you to quickly burn CD, DVD or Blu-ray media with video, music and data.
I love Movavi and I'm sure you will too. Check it out here.

3. Cybelink PowerDirector
Cyberlink PowerDirector is also a contender for best video editing program. What makes this program unique is its concept of "import and capture". There is a standard set of tools present in the programs which allows you to import an existing video that is already present on your computer's hard drive or you can capture a video from portable camera for video recording.
You can also capture a video straight from a DVD - a feature available only in high-end video editing programs. Editing is as simple as it gets - you can tinker with a large number of effects which can be personalized. Want to trim or split a video? That again is a breeze. On the whole, a simple, extremely user friendly and value-for-money editing suite.
4. Adobe Premiere Elements Third in the cue is Adobe Premier Elements and a hot favorite. Besides the fact that it is from a very trusted name in media software (i.e. Adobe), Premiere Elements is capable of a whole host of features.
Uploading a video to the Web or burning a home movie on a DVD can be done with simple commands. The program boasts one-touch transfer which allows you to capture the video output quickly from a DV camcorder. You can also edit photos, narrate audios and create DVD menus. Provided your computer has the minimum system requirements, Premiere Elements is a lot of fun to use and comes highly recommended.

5. Pinnacle Studio Beginner or intermediate level user in video editing? Then you are going to love Pinnacle Studio. There are formats specified for different skill sets and all that you need to do is to choose the one that suits you. This is nowhere close of being an industrial software but the program is definitely good for home users with lovely features and tools for special effects, panning and zooming resolution and much more. The usage of this software is so simple and self-explanatory that you may never want to shift to other programs when you get used to it!

6. Easy Media Creator
Roxio Easy Media Creator is a video editing program that is fast and easy to use. Creating backups and burning them on CD, DVD and Blu-Rayis simple - you can even schedule the burning process!
Easy Media Creator allows you to create soundtracks and playlists for your video. Analog formats can also be converted to digital formats within the software. I'll admit that Easy Media Creator is not as high quality as Corel VideoStudio, Adobe Premiere Elements or Movavi, but the program toolset is certainly still impressive enough. Which is why it makes it to my list of the top 10 nominees for best video editing program.

7. Corel DVD MovieFactory If you need to share video files quickly with others with minimal editing, you are going to love Corel DVD MovieFactory.
MovieFactory focuses on creating a CD, DVD and Blu-Ray disc containing your video production as quickly as possible. There are built-in templates which can be customized - you can spend hours playing with these. You can use the timeline and storyboard to gain control of the video editing process. There's even a nice option to create music videos.
This is a beginners' level video editing program and is a whole lot of fun to use. At intermediate or expert levels, the program is does not really make the cut.

8. Arcsoft The Arcsoft program has a simple appearance but is loaded with features. Hook up your camcorder to the computer to quickly start the video editing process. The program can then run a pre-check your imported video can highlight unwanted scenes to be automatically detected.
Drag and drop the imported clips into the storyboard for better control and visualization. Videos can then be split into smaller clips, audio can be embedded into scenes, while specific themes can be added to the videos. You can also create beautiful slideshows.

9. Sony Vegas Studio Premium
Sony Vegas Studio Premium is a great all-round video editing package that it takes into account the expertise of the user. Whether you are a newbie or professional video editor, the software has the feature set to support you.
What Sony Vegas Studio Premium does is that it recreates a video editing studio right in the comfort of your own home. You can conveniently makes DVD or Blu-ray copies of the videos you produced. Now you can preserve your beautifully shot HD videos into media and distribute them easily to friends and family.

10. Movieplus
If you're a newbie to video editing, Movieplus is well suited to your needs. The software follows a guided, step-by-step process to allow you to create your first video production.
The storyboard allows arranging and sequencing of your clips so that you can easily include the nice scenes and remove the unwanted ones.
Special effects, zooming and trimming are very well implemented and they allow you to transform an otherwise boring video into a professional production complete with solid, crisp effects.
Don't have time to wade through something like Adobe Premiere Pro to create a nice home video? Well, go for Movieplus because it is great for creating super videos with ease and without any professional knowledge.

Conclusion Whether you're a hobbyist shooting a home video, or a professional planning a formal video production, you absolutely need a robust video editing package.
The above 10 video editing programs are the best of the best and will help you preserve memories and produce cutting-edge, beautiful looking videos that you can keep for generations to come. Check out these programs, learn and experiment with them and make your videos better.
P.S. If you asked me to choose, my favorites out of the ten would be Corel VideoStudio, Adobe Premiere Elements, CyberLink PowerDirector and Movavi. You have to experiment to see which one suits you - but based on my experience those four are the ones I usually turn to.

Video DSLRs vs Camcorders

The Dirty Little Secrets

The convergence of stills and video continues. An increasing number of DSLRs now have video capability. The first were the Nikon D90 and Canon 5DMKII, both introduced in 2008. The first half of 2009 has now seen the Canon Rebel T1i (500D), Nikon D5000, Panasonic GH1, and Pentax K7 introduced.
While this site's primary focus is still-image making in all its forms, the convergence movement on the part of the camera industry requires that attention also be paid to video and video making. While there is reluctance on the part of many amateurs to adopt this blending of image making disciplines, many pros have embraced video as a new means of revenue generation, not to mention creative expression. And for creative amateurs it's becoming clear that things don't have to be an either / or decision; a great many leading photographic artists have also been filmmakers, such as Robert Frank, Henri Cartier-Bresson, and Gordon Parks, to name just a few.
Since we expect that just about every DSLR introduced from now on will have video capability, It is worthwhile understanding the difference between what a Video DSLR (AKA – ComboCam) and a Camcorder each have to offer, both for the videographer and the still photographer wanting to get into video.
If the jargon and basic concepts of contemporary video are a bit unfamiliar to you, my Video Primer for Photographers may be of some assistance.

It's About Shallow Depth of Field

Just as in the world of digital stills, there are categories and cameras, and then there are marketing words such as amateur, prosumer, and pro. Depending on who's saying them and the context, these can either be explanatory or pejorative.
Video capable DSLRs like the Canon 5D MKII have been rapidly embraced by professional and indie film makers for what it can do, but not because it is by any stretch of the imagination a professional video camera.
The magic that video DSLRs offer is their large sensors (at last when compared to video cameras). No, not for the purposes of increased resolution. 1080 and 720 are what they are, and a larger sensor doesn't provide any higher resolution. Rather, because these larger sensors allow for narrower depth of field. Of course it's not the sensor size so much as it is that for a given aperture and focal length one gets narrower DOF with a larger sensor as a consequence of their using longer focal length lenses for the same image magnification. This is the holy grail for many film makers: the narrow DOF that allows the videographer to isolate a subject and therefore give the scene a more "filmic" look.
Combined with shooting in 24P (another filmic conceit (Def 4.b)) these are the two characteristics that North American independent film makers (Indies) try for when shooting video. In the rest of the world most video producers just don't get it. That's fine. I'm fairly agnostic on the subject though trending more towards embracing shallow DOF and 24 FPS the more I shoot.
The reason for this preamble is to try and shed some light on why film makers are going a bit nutso over video DSLRs, even though these are, for the most part, not very good all-round video cameras.
They're not – you say? How so?

What We Do and Don't Currently Get with DSLR Video Cameras

As exciting as video-capable DSLRs are for film makers of various stripes, they lack a great deal as video cameras per se. The list below is not intended to be comprehensive, and not every feature lacking is missing on every current video DSLR. Some have one or two desirable video features, others don't. But, for someone who looks at one of the new video DSLRs and says to themselves – self; this is all I need to shoot movies, here's what's often missing or problematic.

Viewfinders and Screen

Serious videographers require both an articulated LCD screen as well as an electronic viewfinder. An EVF allows for more stable shooting when hand-held, and also for clear viewing in bright sunlight. Most current Combocams (the Panasonic GH1 is the only current exception) have just an LCD screen with "Live View" video, and only a handful of the newer models have articulated screens. (A DSLR's optical viewfinder isn't available in LV and video modes).
A fixed LCD makes many types of shooting situations awkward at best. Having only a fixed LCD and no EVF is really like trying to shoot with one eye tied behind one's back – to mix a metaphor.
All pro level camcorders and the top amateur handycams have both, and all higher-end camcorders have EVF's with large eye relief, allowing glasses to be worn. Most are also articulated, so that one can look through the viewfinder while the camera is situated at a low vantage point.

Audio

Of almost equal importance to image quality is audio quality. All video capable DSLRs (Combocams, as I've dubbed them) can record sound, but it's often highly compromised in several ways.
– Less expensive models often only have mono audio recording.
– Because these are primarily still cameras the controls can be noisy to operate and therefore sound can be seriously compromised.
– Audio monitoring is often missing; the ability to listen to what is being recorded through a pair of headphones. Recording sound without audio monitoring is like recording video without being able to see a screen.
– Most Combocams lack the ability to manually set audio levels, relying instead on auto gain control (AGC).
– None of the available or announced Combocams have XLR connectors. Instead they use mini-jacks which, as anyone knows who has used these on location, are the work of the devil. They break and come loose if you look at them the wrong way. XLR connectors are industrial strength and used in pro gear. Anything else is a disaster waiting to happen.

Power Zoom

– Combocams, being DSLRs at their heart, lack power zooms, which virtually all video cameras have as a matter of course. Amateurs use zoom more than is good for them (or their audiences), but having the smoothness of a power zoom mechanism when needed is welcome, and very hard if not impossible to emulate on still camera zoom lenses without expensive and bulky accessory gear.

Redrock Video DSLR Accessories

Peaking and Zebras

– Real video cameras provide two aids to assist exposure and focus, peaking and zebras. Zebras are similar to the flashing highlights that one gets on a DSLR's on-screen review image, but with several advantages. Firstly, they are "live" so that one can adjust exposure before shooting a single frame. Secondly, on most of the better low-end, and all the high-end video cameras, one can adjust the point at which the zebra pattern starts and stops.
Stops, you ask? Yes. For example, you can specify in the menus that the zebra pattern will only show in areas between 80% and 90% of maximum exposure. Anything above 90% will be ignored. This is great for not being distracted by zebraing on specular highlights and also large blown-out areas such as clear skies.
Peaking is the ability to set the viewfinder to show areas of greatest sharpness. On the new JVC HM100, for example, it turns the viewfinder or LCD to monochrome (which some video shooters prefer to work in in any event) and then shows edges of greatest sharpness in the image with a coloured outline, red for instance. Very handy when doing critical manual focus pulls. (Focus Pulls – manually changing focus during a shot to change the viewer's attention to the desired subject.)

Codecs and Data Rates

Various video and still / video cameras use different video encoding schemes. These range from the inefficient (Motion JPG) to the very efficient (AVCHD). I'm referring to efficiency in terms of data compression. Video produces vast amount of data, and high resolution Progressive can be very large indeed.
The bit rate that a camera uses is also a factor. Generally, the higher the bit rate the higher the image quality, but a lower bit rate can be used when a more efficient codec is applied.
This is too great a topic to be explored here, but be aware that there's no free lunch, and you need to understand the bit rate and the codec being used to make meaningful comparisons, and even then a big variable becomes how easy or difficult it is to work with the files.
Until very recently the highest compression codec, AVCHD, has been a real bear to work with efficiently in terms of editing, but that is now (mid-2009) changing for the better.

Resolution and Frame Rates

Proper video cameras shoot at a range of resolutions and frame rates. Current models can typically shoot at 1080i 24/30/60, 1080P 24/30, and 720P 24/30/60. No Combocams have this versatility, at least as of mid-2009.
It is important for many videographers to be able to match with footage shot on other systems. If a Combocam can only shoot 1280 X 720 (720P), for example, and the footage needs to mixed with others that are 1920 X 1080 (1080i), this can be problematic.
Worse are Combocams that shoot bizarre non-standard frame rates, such as 20FPS. Who thought that was a good idea?

Real-Time Output

Articulated LCDs and EVFs are important, but in many production environments, even fairly simple ones like low budget music videos, external monitors are demanded, and this means having live HDMI or component video output. Among Combocam only the 5D MKII, I believe, offers this.

Jello-Cam

Many advanced amateur and pro camcorders use CCD sensors and therefore do not suffer from a rolling shutter; so-called Jellocam, the effect that one sees with CMOS based video cameras, where there is a temporal difference between the time that the top of the frame is recorded as compared to the bottom of each frame. Thus, if the subject moves horizontally during a shot, or the cameras does similarly, the subject will appear to bend.
There are, of course, CMOS-based pro video cameras such as the Sony EX1 and EX3, and the Red One. And, yes, they do display some image distortion on rapid pans or subject motion, but for technical reasons (more sophisticated on-board processing chips) this is far less that is seen with Combocams.

No ND Filters

With still cameras one uses shutter speed and aperture to control exposure, along with ISO. When shooting video one has "Gain" instead of ISO, but shutter speed isn't really available, unless one is looking for a special effect, and aperture availability is limited because with small sensors one pretty quickly gets into diffraction at smaller apertures and therefore reduced resolution.
For this reason video cameras have built in neutral density filters which can be dialed in in one, two or sometimes three stages. This enables shooting at wide apertures, even in bright sunlight. No Combocam has this capability.
Screw-in ND filters can of course be added to Combocams, but they are slower to use and therefore less convenient.

The Bottom Line

Video capability in DSLRs represents nothing short of a revolution. A new generation of photographers will embrace what they have to offer and use them to create new forms of art and commerce. In a few years we'll likely think that a still camera that can't also shoot video, or a video camera that can't also shoot stills is strangely underfeatured.
Still photographers will embrace them because they provide a new tool; a new possible means of creative expression. Videographers and movie makers will adopt them because they provide convenient access to that most desirable of traits in film making: shallow depth of field.
Does a Combocam obviate the need for a video camera? Should commercial photographers adding video capability to their repertoire just use one of these, rather than also working with a Camcorder?
It's feasible, but I would advise against it. For all of the reasons listed above, a Combocam, as good as it can be, is limited in its features and capabilities, and therefore there will remain a great many things that they simply can't do, or at least can't do all that well.
Does every still photographer need video. No – of course not. Many don't, and will resent the focus on them (so to speak). I'm old enough to remember when TTL metering, auto exposure, zoom lenses, autofocus, and of course Digital were all new, and all were disparaged by the cognoscenti. That's OK. Being an "old fart" has nothing to do with chronological age, but everything to do with head space.
